Have you checked the flasher? Uses an automotive type flasher. Is about 3/4 round X 3/4 high with two plug in wires. Probably under the tank or under the seat.
Have you checked the lamps? Front and rear should both use dual fliament lamps. Replace with the same number, available at automotive or motorcycle parts place.
Lower your bike? As in put it closer to the ground? Unless you are an engineer, don't mess with the geometry --- really --- you will put yourself as well as everyone you enconter on the road (including me and my family) at grave danger!!!

My friend, a motorcycle is not like a riding lawn mower. Everything on a motorcycle is designed to be a part of that motorcycle. Every system is balanced against every other system. When you start reengineering without experience or training, you are endangering yourself and others. You can also damage your engine and other systems.
When it comes to motorcycles, 'If in doubt, DONT'.
Please enjoy your classic motorcycle and the restoration project you are involved in.
